SOLE-SHAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 409,269, dated August 20, 1889.

Application filed December l0, 1887i Serial No. 257,500. (No model.)

To all whom t may concern: `slight oscillating movcment,to the end that it Be it known that I, TIMOTHY A. BREsNA- may adapt itself to the inequalities of the HAN, of Lynn, in the county of Essex and sole. i Commonwealth of Massachusetts, have in- Therod I-I is arranged, as shown,in block R, 55 5 vented certain new and useful Improvements and is provided with a suitable thread adapted in Boot and Shoe Sole Shaping Machines, of to work in screw-wheel M, also mounted in which the following, taken in connection with the block R, in such manner that turning the thc accompanying drawings, is a specification. wheel operates to move the rod longitudinally This invention relates to machinery for in the block. Said block R has its lateral 6o ro shaping boot and shoe soles after they are atedges grooved or concaved to fit the rods P P, tached to the shoe-upper. It is an improvcby and between which it is supported and ment on the machine described in Letters Patalong which it is reeiprocated longitudinally ent of the United States numbered 300,039, for the purpose of forcing the mold forward dated June l0, 1384, and has for its obj ect to against the sole. The said longitudinal move- 6 5 f5 provide mechanism for applying compressive ment of the block R is effected by the toggleforce to the sole intermittently. It relates, arms a a, and these,in turn, are operated bya also, to minor improvements in matters of consuitable crank-and-lever mechanism., as shown struction,all to be hereinafter fully described, in the drawings, and more fully described and pointed out in the claims. in Letters Patent No. 300,039, above referred 7o zo In the drawings, Figure l is a plan view of to. The toggle-arms d d engage one with the a machine embodying two duplicate sets of sliding block R, and the other with a plunger mechanism, and each set embodying my ine, arranged to permit sliding movement in the vention.

Said barrel is mounted upon and of the parts in section. fixed to the machine-frame, and has a chamber 75 15 For a description of details of construction for holding the spring f, which spring is coiled and mechanism and as an aid in understandspirally around the plunger-rod,as shown,and ing this invention, reference may be had to bears one end against the rear face of the the Letters Patent No. 300,039. plunger and its opposite end against the bar- The working parts of the machine are rel-head, as shown, and this, it will be under- 8o 3o mounted upon a frame-work A.

The mold D is formed with past the center line,77 as shown in Fig. 2, in

The next upward nected to a block E, which block E has its throw of the crank-shaft 3 will bring upward lateral edges grooved or concaved to fit the the toggle-arms a a, thereby contracting the 95 45 rodPP,byand between which it is supported, spring f and driving forward the form D and along which it is reciprocated longitudiagainst the shoe-sole for the purpose of moldnally for the purpose of carrying the mold up ing and shaping the same. to and away from the sole. Said block bears The compressive force, it will be observed, its rear face against the rod H, by which itis is applied to the mold through the intermediroo 5o pressed forward. The contiguous faces of ate spring f, which gives ayielding qualityto these parts are rounded and the block permits the pressure. The compressive force is de- `veloped by contracting the spring, and is lifted to an approximately straight line, as-

shown in Fig. 1. This takes place when the crank mechanism is at its highest lifting-point, and the next movement of the crank depresses the toggle-arms a a, and thereby allows the spring f to expand and remove pressure from the sole. The pressure is reapplied by the next upward movement of the crank, as before described, and so on. The pressure is applied and Withdrawn alternately during each complete revolution of the crank, and the shoesole is thus compressed intermittently, to the end that any hard bunches in the leather may be Worked down to an even and uniform surface.

It is desirable that the sole should be subjected to the action of the shaping mechanism for a considerable time, (more or less,) depending upon the kind of Work, and for the purposes of convenience, as Well as economy in manufacture and use, several sets of mechanism-a half-dozen, more or less-may be united in one frame and run by one drivingshaft. The Workman,having adjusted a shoe in one set of mechanism, may turn his attention to placing a shoe on the next adjoining` set of mechanism, and so on he passes through the entire set and comes back to the rst shoe,

which by this time has been quite molded and is ready to be removed.

I claim and desire by Letters Patent to secure* l. In a machine for shaping boot and shoe soles, a form, as B, for supporting` the shoe, a mold, as D, for shaping the sole, toggle-levers a a, means for operating them, a barrel b in rear of one of the levers, a spring inclosed in said barrel, and a plunger in connection with the lever a, fitting said barrel and adapted to be acted upon bythe spring tl1erein,substan tially as described.

2. In a boot and shoe sole shaping mechanism of substantially the construction described, and in combination, the described form for supporting the shoe, a mold, as D, for shaping the sole, a movable block for supporting the mold and adapted to permit a rocking movement, as described, a rod, as H, adapted to bear upon and press forward the block, said block and rod having their contiguous faces rounded, and connecting and operating mechanism, substantially as described.
